D. W. Winnicott’s remarkable books, including The Piggle, Home Is Where We Start From and The Child, Family and the Outside World (all published by Penguin) are still read, valued and argued with over thirty years after his death. Adam Phillips’s short book, now issued with a new preface, is an elegant, thoughtful attempt to get to grips with a writer, paediatrician and psychiatrist whose work with children and mothers (and the wider implications their relationship has for all of us) continues to be profoundly relevant and fascinating.
